    • Yes. Related by time of occurrence. I can handle criminals in Antioch. What I have a hard time with is under- educated over-opinionated people like you. You would do the city a service by crawling on your belly back to the rock from under whence you came.

      • If you’re relatively new to Antioch you’d best get used to it. The place is crawling with uneducated ( on purpose!) knuckleheads. Enjoy the coming desert heat

    • Two shootings in ANTIOCH? Just hours apart? I AM SHOCKED! Totally SHOCKED! One way to look at it is maybe the criminal element can wipe each other out.

      • Michael Moreno is the second fatality of that day! He was NOT a criminal and he didn’t live a criminal lifestyle!
        He was a good man. Had a very SUCCESSFUL Martial Arts Studio, and had MANY students who loved and respected him. He was a Military Man who was in the Special Forces for 5 yrs. He was a RESPONSIBLE, LOVING, RESPECTFUL MAN who was shot down in cold blood!
        Before you start implying someone is of the criminal elements, make sure you know what your talking about!

        • Hi Kathleen,
          Your defense of Mike is too be respected! He was a good man! Unfortunately he apparently rented a place from an individual who wasn’t. I met him in my mid 20’s (20 years ago) through one of his childhood and mutual friends. I received a yellow belt from him in San Soo before he closed that school and joined the military so he could serve our country (a year or two after 9/11). I’ve seen him in situations where he was in the right to be angry but kept his composure. He was a good Christian man who is now with The Lord!

    • Black Plaque? Two less? You’re so far off from the truth it’s pitiful! First off they aren’t black! Second, look up MICHAEL MORENO’S PROFILE!
      He was murdered in COLD BLOOD.
      He was not a criminal in any sense of the word.
      Look up his profile to see what kind of a man he was! You’ll be surprised at how far off your opinion is of him! He was a role model, loved and respected! He was a honest loving, giving man! Please check him out before making your RUDE, DISRESPECTFUL REMARKS ABOUT SOMEONE YOU KNOW NOTHING ABOUT!
